VALVE-OPERATING MECHANISM.

Specification ofLctters Patent.

Patented Apr.'6, 1915.

Application filed October 16, 1913. .js crial N0.79,5,607.

. nisms for gas valves and has-for itsobject the production of an automatic device for cutting off the flow of gas through a pipe when the magnets carried thereby are energized. v

Another object of the invention is the production of a device which may be set so as to allow a gas valve-to remain open under certain circumstances but which may be operated for closing. the gas valve.

IVith the above and other objects inview this invention consists of certain novelcombinations, constructions and arrangements -of parts as will be hereinafter fully described and claimed. 1

In the accompanying drawings :Figure 1 is a top plan view of the valve operating mechanism. Fig. 2 is a vertical section through the casing which supports the operating means for closing the valve. Fig. 3 is a vertical section through the casing taken at right angles to Fig. 2, showing the valve operating mechanism in side elevation.

By referring to the drawings it will be seen that 1 designates a casing. This casing contains an automatic valve closing mechanism to be hereinafter described.

The automatic valve closing mechanism is placed in the casing 1 as above stated and comprises a base plate 3, which base plate supports a pair of magnets 4. These magnets 4 are electrically connected to the binding posts 5 and 6 for allowing the lead Wires 7 and 8 to be connected thereto for the purpose of actuating the armature 9 when the magnets 41 are energized through the wires 7 and 8. The armature 9 is provided with a curved projecting finger 10, which is adapted to engage the trip arm 11, which trip arm 11 is supported upon or connected to the shaft 12. The shaft 12 is journaled upon brackets 13 so as to support the trip arm 11 and this trip arm 11 is engaged by means of a spring 14 in order to urge the trip arm in one direction for releasably retaining the pawl 15 in engagement with the by .the shaft .12 as is clearly illustrated in Figs. 1 and2.

'The brackets 13 are provided with up- .wardlyextending; arallel arms 17 andbetween these arms 1 ;;;there are positioned the ratchet heel;16-and coil spring 18. This coil spring 18 and ratch t wheel 16 are mounted up.on;.a,central shaft 19, and this shaft 1 9.hasa threaded projection 20 which is'adapted to be engaged by a key 21 for the purpose of allowing thespring 18 to be woundinorderthat the valve 22 may be opened. The opposite end of the shaft 19 is connected by "means of a pivotjoint 23 to the valve 22 which valve works in a casing 24:1for-thepurpose of cutting ofl" the flow of gas through the pipe 2.

One of the brackets 20 is held in a vertical position by means of the clip 25 which fits. thereover, this clip being retained upon the'plate. 3 by means of the nut and bolt shown at .26. The other bracket is heldin .a vertical position by the strip 27 which From the foregoing description it willbeseen that as the magnets tare energized,the

armature 9 will be attracted causing the finger 10 to engage the trip arm 11 which arm will cause the shaft 12 to pivot for urging the pawl 15' out of engagement with the ratchet wheel 16 thereby allowing the coil spring 18 to unwind and rotate the valve 22 to a closed position.

Having thus described the invention what is claimed as new, is

1. In an automatic gas shut-ofl, the combination of a supporting casing, electromagnets carried within the lower portion of said casing, a supporting plate carried within said casing above said magnets, a pair of parallel arms carried upon said plate, a shaft carried by said parallel arms, said shaft being adapted to engage a valve cook, a ratchet wheel keyed to said shaft, a coil spring carried by one of said arms and engaging said shaft for urging said shaft in one direction, means releasably engaging said ratchet wheel for normally holding said wheel against rotation and means carried by said first-mentioned means and cooperating with said electro-magnets whereby said last-mentioned means will actuate ratchet-wheel lo. The pawl 15 is carried said first-mentioned means when said magnets are energized.

2'. In a device of the class described the combination of a supporting casing, electromagnets carried within said casing, a pair of parallel arms carried within said casing, a rotatable shaft carried by said arms, said shaft being adapted to engage a gas-valve cock, a ratchet wheel keyed to said shaft, a coil spring engaging said shaft for urging the shaft in one direction, a secondary shaft journaled Within said casing having an integral pawl, means for releasably holding said pawl in engagement with said ratchet wheel, an armature carried adjacent said magnets, and means engaging said secondary shaft and lying in the path of travel of said armature, whereby said armature may move said means and thereby cause said secondary shaft to be moved for swinging said pawl from engagement with said ratchet wheel, whereby said spring will move said first-mentioned shaft for operating the gas valve cock.

3. In a device of the class described, the combination of a casing, electro-magnets carried within said casing, an armature carried adjacent said magnets, means for energizing said magnets whereby said armature may be moved, a shaft rotatably supported within said casing, said shaft being adapted to engage a gas-valve cock, a ratchet wheel keyed upon said shaft, means for urging said shaft in one direction, a secondary shaft carried within said casing and provided with an integral pawl, a coil sprin carried by said secondary shaft for releasably holding said pawl in engagement with said ratchet wheel, a trip arm secured to Copies of this patent may be obtained for said secondary shaft, a finger carried by said armature and adapted to engage said trip arm, whereby when said armature is actuated said trip arm will swing said pawl from engagement with said ratchet wheel and allow said first-mentioned shaft to rotate for turning the gas-valve cock.

4. In a device of the class described the combination of a casing, electro-magnets carried within said casing, an armature carried adjacent said magnets and provided with a finger, a plate fixedly carried within said casing above said magnets, parallel arms carried by said plate, a rotary shaft carried by said arms, said shaft being adapted to engage a gas-valve cock, a ratchet wheel keyed to said shaft, means for urging said shaft in one direction, a secondary shaft carried by said plate, a pawl formed upon said secondary shaft, means for releasably retaining said pawl in engagement with said ratchet wheel, a trip arm secured to said secondary shaft, said trip arm extending downwardly into the path of movement of said finger, whereby when said armature moves said trip arm by means of said finger said trip arm will move said secondary shaft for swinging said pawl from engagement with said ratchet wheel, whereby said first-mentioned shaft will be released for operating the valve.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
